IMPROVEMENT IN MACHINES FOR POUNCING HATS.

Specification forming part of Letters Patent No. 200,118, dated February5, 1878 application filed March 8, 1877.

To all whom it may concern:

Be it known that I, GEORGE YULE, of the city of Newark, in the county ofEssex and State of New Jersey, have invented certain new and usefulImprovements in Machines for Pouncing Hats 5 and I do hereby declarethat the following specification, taken in connection with the drawingsfurnished, is a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the same.

My invention consists in the construction of a machine for pouncing hatsin such a manner as to enable the operator to control the motion of theblock without the assistance of the hands, whether it be for the purposeof increasing or decreasing the speed, or otherwise, so that the workmanmay have full and complete control over his work; the object of which isto secure the best viinish to the hat `without the usual liability toreduce the material at points where the body of the hat may be thin,which is usually caused by the process of sizing and forming. It alsoenables the operator to examine his work, and thereby guard against toomuch application of the finishing material to one part and not enough atanother. It also avoids the sudden jars incident to such machines whenthe driving mechanism is stopped entirely,as is usual in machines of theordinary style of construction. Machines of the latter class, owing tothe great speed required in practice, when frequently stopped, asbecomes necessary in the operation of finishing, wear Very rapidly, andare not only apt to become broken by the sudden starting, but requiremuch more power to start the same than is needed for machines employingmy improvement.

Referring to the drawings, Figure l represents a front view of mymachine. Fig. 2 represents a section of my improvement.

A represents the frame. B is a vertical shaft, upon which the block O issupported and revolved. D is a rack, horizontally arran ged,which issupported and guided in ways, which rack is operated by rod F throughthe medium of crank-wheel G, which unites with a pinion, E, by whichmeans the'lblock is partially revolved back and forth. H and H representmy friction-clutch for operating the same, application and formation ofwhich will be readily understood upon reference to the drawings. V Y

The operation of my improvement may be described as follows: It will b eobserved that a foot-lever, X, is arranged at or near the bottom of thevertical shaft B. This lever is arranged to elevate the vertical shaft,which is represented as being capable of sliding vertically in itsbearings. The male part of the clutch, being fast upon the shaft, riseswith it and engages the counterpart above, which counterpart is securedto the pinion, which is in continual motion. The engagement with thepinion causes the vertical shaft, with its block, to revolve with agreater or less rapidity, according to the pressure applied to thefoot-lever below. For a slow motion a slight pressure only will berequired, which may be varied according to the seeming requirements ofthe operator.

Having thus set forth my invention, what I claim as new, and desire tosecure by Letters Patent of the United States of America, is-

l. In a machine for pouncing hats, the combination of alongitudinally-movable blockcarrying rod with a friction-clutch andoperating mechanism, substantially as and for the purposes set forth.

2. In a machine for pouncing hats, the combination of a slidingfriction-clutch and blockcarrying rod with a treadle for throwing saidclutch into gear, substantially as set forth.

3. In a machine for pouncing hats, the combination, with its verticalshaft, block, and clutch, of the reverse operating mechanism,substantially as described, whereby the block is moved in two directionswhile being operated upon, substantially as set forth.
